SELEMIX® brand ISO 12944

ISO 12944 was published in 1998 as both a European and International standard and it is the highest worldwide and qualified standard reference for effective corrosion protection of steel structures.
It covers protective paint systems designed for application to uncoated steel, hot-dip-galvanized steel and steel surfaces with thermally sprayed zinc coatings.

ISO 12944 includes 8 different sections covering issues such as the measurements of the corrosivity of various environments, surface preparation and laboratory testing procedures.
An external laboratory has tested the main 2K Selemix paint cycles based on the International standard ISO 12944 qualifying them in the corrosivity categories and durability ranges in accordance with ISO 12944-6 ( Laboratory performance test methods).

According to the test results obtained please find the laboratory reports and a table which summarizes the classification or Selemix paint cycles in each corrosivity category and durability ranges.
